MU8

Android/Kotlin Marvel sample app created during the Architect Coders program.

This repository is included in my public portfolio as evidence of Android architecture practice, collaboration, and testing in a multi-module codebase. It is a learning project, not client work.

Project Context

MU8 was developed as part of the Architect Coders program by Antonio Leiva. The app explores Marvel content such as characters, comics, and events while applying layered Android architecture and team-based delivery through issue branches.

Architecture

  • presentation: Android UI, Activities, ViewModels, adapters, data binding, UI tests, and dependency wiring.
  • domain: use cases, repository contracts, domain models, and business-facing abstractions.
  • data: Retrofit services, Room persistence, entities, DAOs, mappers, and repository implementations.
  • buildSrc: centralized dependency/version declarations.

What This Demonstrates

  • Multi-module Android project structure.
  • Clean Architecture-inspired separation between presentation, domain, and data.
  • MVVM-oriented presentation layer.
  • Repository contracts and implementations across domain/data boundaries.
  • Retrofit-based API integration.
  • Room-based local persistence.
  • Dagger dependency injection.
  • Unit tests, UI tests, MockWebServer, and Espresso.
  • Detekt configuration for static analysis.
  • Collaborative development through feature and issue branches.

Notable Branches

This repository keeps several branches that show how work was split by feature, issue, and contributor. Examples include:

  • feature/recaldev/issue-31-room-setup
  • recaldev/feature/di
  • recaldev/feature/events-unit-tests
  • mu8/recaldev/ui-tests
  • mu8/santiago/issue56-characters-unit-tests
  • feature/santiagolozada/issue57-add-integration-test-characters-flow

Notes

This project uses an older Android stack from the time of the course. It is valuable as architecture and collaboration evidence, not as a current dependency baseline.
